How to fix supply sensor not connected error on PEERLESS PureFire PF-110?
- EEugene PenaSep 5, 2025
If your PEERLESS Boiler displays the error 'SUPPLY SENSOR NOT CONNECTED', check the harness and sensor.
How to fix supply sensor not connected error on PEERLESS PureFire PF-110?
If your PEERLESS Boiler displays the error 'SUPPLY SENSOR NOT CONNECTED', check the harness and sensor.
How to troubleshoot ignition error on PEERLESS Boiler?
If you are experiencing an ignition error with your PEERLESS Boiler, follow these steps: 1. Watch the igniter through the observation window. 2. If no spark is present, check the spark electrode for the proper 3/16" gap. 3. Remove any corrosion from the spark electrode with abrasive. 4. If spark is present but no flame, check the gas supply to the boiler. Check for high or low pressure. 5. If there is a flame, check the flame signal ignition log in the Installer Menu. If values for flame signal are less than 3.1 µA, check wiring connections and clean the harness connector at the control. 6. Determine if gas valve is opening by monitoring gas pressure. 7. Check gas pressure.
What to do for false flame detected after shutdown on PEERLESS PureFire PF-110?
If your PEERLESS Boiler displays 'A19 - FALSE FLAME DETECTED AFTER SHUTDOWN', check the flame sensor and igniter to ensure there is no short to ground. This error may also indicate that the gas valve isn’t closing completely.
Why is the return higher than supply on my PEERLESS Boiler?
If you see 'RETURN HIGHER THAN SUPPLY' on your PEERLESS Boiler, check the system piping to ensure water enters the return connection and exits the supply connection correctly. Also, compare the supply thermistor reading to the temperature gauge; if they don’t match, replace the supply thermistor.
How to fix poor ground error on PEERLESS PureFire PF-110 Boiler?
If your PEERLESS Boiler is showing 'POOR GROUND' error, check the boiler ground and harness.
What causes high stack temperature in PEERLESS Boiler?
If your PEERLESS Boiler has a 'HIGH STACK TEMPERATURE', and the flue pipe is hot, check the flue temperature and compare it to the values in Table 8.5. Also, inspect for proper gas input and combustion readings, and check for a dirty heat exchanger. If the flue pipe is not hot, check the flue sensor and harness.
How to troubleshoot a blocked vent in PEERLESS Boiler?
If you have a blocked vent in your PEERLESS Boiler, check for a blocked vent pipe or blocked heat exchanger. Also, check the switch and tubing connected to the switch.
What to do if PEERLESS PureFire PF-110 Boiler showing false flame detected?
If your PEERLESS Boiler shows a 'FALSE FLAME DETECTED' error, first verify there is no flame in the observation port, then check the sensor.
How to fix hot/neutral reversed error on PEERLESS PureFire PF-110 Boiler?
If your PEERLESS Boiler displays the error 'HOT/NEUTRAL REVERSED', verify the polarity of the incoming wiring and check the boiler ground and harness.
What to do if there is a false flame detected before ignition in my PEERLESS PureFire PF-110?
If you're experiencing a false flame detected before ignition with your PEERLESS Boiler, check the flame sensor and igniter to ensure there are no shorts to ground.
